CORPORATION OF DELAWARE INSULATOR-SUPPORTING EIx'rU E A Application filed. July 12,

1 This invention relates to certain new and useful improvements 1n insulator supporting,

fixtures and refers more particularly to what is generally termed in the art as a secondary rack employed for carrylng secondary wires I along poles and other places.

In the production of supporting fixtures of the character described, it is of utmost importance that they be of sufiicient strength to withstand all stresses, at the same time being capable of economical production to compete with the market and this invention has as an object to generally improve and simplify the construction of secondary racks ably stamped from a one-piece blank and which is of rigid and substantial construction. c x A I With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantiallyas hereinafter described v and more particularly defined byjthe appended claims, it being understood that such.

changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

v I f In the accompanying drawing, I have illustrated one complete example of the physical embodiment of'my invention constructed ac.-

cording to the best mode I have so'far devised forthepractical application of the principles thereof, and in which:

Figure 1 is a perspectiveview of an insu- A lator supporting rack or supporting fixture embodying my invention, and Y Y 1926 Serial No. 121,868.

' Figure '2- is a view, partly in section and f partly in elevation, taken" through Figure on the plane of the line22.

The improved fixture is formed from a single blank} 5 having medial, transversely extend ng, recesses definingtransverse-strips or straps 6 forming laterally projecting spaced bracketarms 7 when the'blan'k is folded 1on gitudinally upon itself along a central line The cut-away or recessed portions have tongue portions 8 extended thereinto from one end and flanges 9 extending thereinto from the sides. Inthefinished structure,

the tongueportions 8 are bent 'toform' ties with their free ends directed inwardly'and riveted'or otherwise secured, as at "10, to the other half or section of the blank to prevent spreading. The flanges 9fare: directed inwardly and adjacent flanges abut, as illus trated in ithe drawing,"toreinforce the bracket arms andv close the-top and bottomportions thereof; 7

The longitudinal marginal edge portions of the: blank are flanged laterally to form at taching flanges 11 provided with'apertures 12 for receiving lag screws orother means 13. for se'curingthe fixture? to a suitablesupport, indicated as at 14. 7

7 Pin receiving apertures 15 are formed in the outer ends .ofthe bracket arms, by the fold of'the' blank to receive a mounting pin 16 which passes throughithe apertures and through insulating spools 17 inserted in the space between adjacent bracket arms, the flanges 9 retaining the mounting pin at the fold of the blank as will be readily apparent. I It will thus be apparent that comparatively thin sheet stock'may be employed in the formation of, my'improved fixture without the sacrifice of strength, as the flanges 9 provide ample reinforcement forthe bracket arms :which are substantially rectangular shape in cross section,b'eingformedfin two,

channeled sections having the edges of their side flanges abutting,and that the base of the fixture is strongly reinforced by the ties 8, A

thus producing a very economical, strongand practical fixture. j 7 c A WhatI claim as my-invention is 1. An insulator supporting 'fixture integrally formed from a single blank of bendable metal, comprising a plurality of bracket arms folded upon themselves at their outer ends, the fold of the material dividing the fixture substantially into complementary sections and forming aligned pin receiving apertures at the outer end of the bracket arms, attaching flanges at the base of the bracket arms for securing the fixture to a support,

and a tongue connecting the complementary sections of the fixture between adjacent bracket arms.

2. An insulator supporting fixture inte-' grally formed from a single blank of bendable metal, comprising a plurality of bracket arms folded upon themselves'at their outer ends, the fold of the material of said outer ends forming aligned pin receiving apertures, inwardly directed marginal flanges on the edges of the arms whereby the halves of the bracket arms are substantially channel shaped toreinforce the same, an integral tongue part propjecting from one side of the fixture be tween the bracket arms, means securing the free end of the tongue-part withthe other side of the fixture whereby the halves of the bracket arms are held against spreading, and

lateral attaching flanges at the marginal edges of the fixture for securing the same to a support.

3. An insulator supporting fixture integrally formed from a single piece of bendable metal, comprising spaced substantially U shaped arms whose closed ends are adapted to i receive an insulator mounting pin, the sides of the U shaped arms on each side of the fixture forming continuations of each other at their base, a tongue extended from the continuation of the arms, at one side, means securing the free end of said tongue with the continuation of the arms at the other side to prevent spreading of the sides of the U shaped arms, and attaching flanges at the base of the arms for securing the fixture to asupport.

v In testimony whereof I aflix my signature.
